Background
The opening and closing piece of the ball valve is driven by the valve rod and rotates around the axis of the ball valve. The hard seal V-shaped ball valve can also be used for regulating and controlling fluid, wherein a V-shaped ball core of the hard seal V-shaped ball valve and a metal valve seat of the build-up welding hard alloy have strong shearing force, and the hard seal V-shaped ball valve is particularly suitable for media containing fibers, tiny solid particles and the like. The multi-way ball valve can flexibly control the confluence, the diversion and the switching of the flow direction of the medium on the pipeline, and can close any channel to connect the other two channels. The valve of this type should be generally installed horizontally in the pipeline. The ball valve is divided into: pneumatic ball valves, electric ball valves, manual ball valves.
However, when the ball of the ball valve moves, the fluid in the valve body is squeezed, resulting in an increase in the pressure in the valve body, which is likely to cause the valve body to burst. Accordingly, the present invention is directed to an electric explosion-proof ball valve that solves the above-mentioned problems.
